This invention relates to air conditioning apparatus and relates more particularly to devices or coolers for supplying cool air to rooms and othercompartments. A general object of this invention is to provide an apparatus of the character referred to embodying a novel highly effective means for mounting the same in a window opening or similar aperture.

The present invention is primarily concerned with devices usually known as evaporative g coolers which serve to supply cool air to rooms and other compartments of building structures and is particularly concerned with the type of cooler that is-to be positioned in a window opening or s milar aperture. Considerable difilculty has been encountered in providing a practical means for supporting or mounting such evaporative coolers in the window openings, etc. An important object of this invention is to provide a positive dependable and universally adaptable means for mounting or supporting an air conditioning device or cooler in a window opening or similar aperture.

Another object of this invention is to provide an apparatus of the character referred to in which the weight of the device is transferred to the building structure at spaced points thereby relieving the cooler, window frame and building parts of concentrated loads.

Another object of this invention is to provide a cooler or air conditioning apparatus of the character referred to in which the cooler is engaged or hung in the window opening. or the like, in such a manner that it tends to swing downwardly and inwardly toward the external face of the buildin and adjustable means are provided for resisting such tendency. The ad-= justable means are carried by the cooler at spaced points and are engageable with the outer face of the building to transmit the load directly to the building. By adjusting these means the cooler may be brought to its correct upright position and may be maintained in the correct operating position throughout its period of use.

Another object of this invention is to provide an apparatus of the character referred to in which a simple rigid frame carries the heavy ..r principal elements of the apparatus and the above mentioned adjustable support means are likewise carried by the rigid frame so that the loads transmitted by the adjustable means are transmitted directly to the frame and do not distort or strain the casing.

Another object of this invention is to provide an apparatus or cooler oi the character mentioned that is simple and inexpensive to manufacture a'...l that is very easy to install.

The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of my invention, throughout which description reference is made to the accompanying drawing, in which:

Fig. 1 is a perspective view showing the cooler of the present invention mounted in positionat the window opening of a building structure. Fig. 2 is a perspective view at the inside of the window illustrating a portion of the ,mounting means or adaptor means. Fig. 3 is an enlarged vertical detailed sectional view showing the ap paratus in position on the building with portions of the apparatus in side elevation, "Fi 4 is an enlarged fragmentary horizontal detailed sectional view illustrating the manner in which the side sealers fit the window opening. Fig; 5 is an enlarged iragmentary horizontal detailed sectional view illustrating one of the adjustable means for hearing on the outer face of the building and Fig. 6 is a vertical detailed sectional view taken as indicated by line BB on Fig. 5.

The apparatus of the invention may be employed or installed in situations varying greatly in character. In the drawing 1 have shown a typical installation where the device is installed at the window opening of a building structure to deliver cool air to the interior of the structure. It is to be understood that the invention is not to be construed as limited or restricted to the specific embodiment of the invention illustrated or tothe particular use or application;

The building structure illustrated comprises a wall it provided with a window opening. The window opening is equipped with the usual frame ii and sill it. A window it is movable vertically in the window frame and in the draw ing is shown in a partially raised. position.

The cooler or apparatus of the present invention may be said. to comprise, generally, a housing or casing it, a supporting frame it within the casing it, air handling means is carried by the frame it and operable to create a movement of air, adaptor means i? engageabie in the window or frame ii to support or partially support the cooler and to direct the moving air into the building, and adjustable means i8 carried by the frame it for hearing on the exterior of the wall it to maintain the cooler in the hori zontal operative position and to assist in transmittlng the weight of the cooler to the building structure.

In the typical embodiment of the invention illustrated in the drawing the casing i4 is an upright generally rectangular structure and the casing is hollow to house and contain the workin parts. etc. The top I9, bottom 20 and inner wall 2| of the casing |4 may be closed or imperforate. The forward wall and the two opposite side walls of the casing M are perforate to admit the out- -side air and, in the case illustrated. these walls of the casing have horizontal louvers 22. The

particular casing |4 has a width somewhat less than that of the window opening and is of substantial vertical extent to project downwardly beyond the window sill I2 when in the operative position. Insofar as the present invention is concerned the casing |4 may be a simple sheet metal structure.

The supporting frame l5 serves to mount the various working or operating parts within the casing l4 and carries the adjustable thrust transmitting means |B. While the supporting frame |5 'may vary considerably in construction it preferbers 23, 24 and 25 of each frame unit are rigidly secured one to the other to constitute a strong unyielding triangular framework. The upper portions of the vertical members 23 may project upwardly beyond the members 25 and the horizontal frame members 24 are preferably spaced above the bottom to leave a pan or a space for receiving a pan. As best illustrated in Fig. 1 of the drawing the triangular frame unit made up of the members 23, 24 and are spaced inwardly from the adjacent side walls of the casing |4, although this is not always essential. It is to be understood that the rear casing wall 2| and other elements of the casing may be secured to and carried by the two frame assemblies or units.

The air handling means i5 may vary in nature with different sizes and uses of the apparatus. In the case illustrated the means l6 includes a centrifugal type blower having a volute case 28 and a centrifugal type blower wheel 21 within the case. The case 26 is housed within the casing i4 and has its discharge end or outlet facing inwardly and located at the inner wall 2| and adjacent the upper end of the casing. The side walls of the volute blower case 26 have air admission openings 28. 'The volute case 26 is disposed between the two triangular frame units made up of the members 23. 24 and 25 and may be secured to the frame units and to other parts of the casing such as the rear or inner wall 2|. The centrifugal wheel 21 of the blower is carried by a shaft 23 which projects from the opposite ends of the volute case 25. The projecting end portions of the wheel shaft 23. are mounted in suitable bearings fixed on the angular frame members 25. Any suitable power means and drive may be provided for operating the blower, In the case illustrated, an electric motor 3| is of the water in the packs.

mounted on one of the sloping frame members 25 to operate the blower. A suitable belt and pulley drive 32 having the desired speed reduction is provided between the motor 3| and the adjacent end portion of the shaft 29. Air filter packs 33 may be mounted in the casing M at its several louvered sides and where the apparatus is to serve as a cooler and humidifying device these packs are supplied with water to obtain the cooling and humidifying action by the evaporation I have shown a pipe or tube 38 leading into the casing I4 to deliver water to the packs'33. The present invention is not primarily concerned with the details of the packs 33 or of the water handling means and these elements are omitted from the present disclosure. It is to be understood, however, that the filter packs and water circulating elements may, if desired, be mounted on the two triangular units of the supporting frame i5.

The adaptor means i7 operates to mount the device at the window to deliver or direct the air from the blower into the building structrure. The adaptor means I! includes a tubular adaptor 34 leading from the outlet of the blower case 26. The outlet of the blower case 26 may be square or rectangular and the adaptor 34 may be of the same shape. The adaptor 34 is secured to the blower case 26 and may be secured to the casing I4 and projects horizontally from the rear or inner wall 2| of the casing l4. The adaptor 34 is of sufficient length to project completely through the window frame II with the casing l4 spaced away from the external face of the wall I0, as illustrated in the drawing. A vertical or down turned flange 35 extends along the lower side of the adaptor 34 at its inner extrernity to engage with the inner face or edge of the sill i2. The lower side of the adaptor 34 may rest on the sill i2. The inner end of the adaptor 34 may be equipped with a suitable grill ncls 4| of the sections 31.

- adjustably connected or associated with the sec- Theadaptor means further includes closures or seals for closing those portions of the window opening at opposite sides of the adaptor 34 and which occur by reason of the window 3 being raised to a position above the adaptor. In some installations the seals may consist of simple plates or sheets secured to the opposite sides of the adaptor 34 and cut to size at the job to close the opening. In the construction illustrated there are adjustable seal assemblies for closing the opening. There is a closure or seal assembly at each side of the adaptor 34. Each of these assemblies includes a stationary closure section 31 secured to a side of the adaptor 34. Angie irons 39 may secure the sections 31 to the sides of the adaptor 34. The closure sections 31. are of the same vertical extent as the adaptor 34 and are vertically disposed in or adjacent the plane of the window l3. The stationary sections are U-shaped or channel shaped having channels 4|. Each assemblyof the closure means further includes a shiftable or adjustable section 40. The

' sections 40 are vertically disposed plate-like members of the same vertical extent as the sections 3'! and arranged to ride or shift in the chan- The sections 40 are tions 31 so that they may be moved in and out as occasion may require. It will be seen that when the adaptor 34 is engaged through the window opening to have its flange 35 cooperate with the inner edge of the sill I2 that the shiftable closure sections 40' may be moved in or out to bring their aaaasao outer edges into cooperation with the side parts of the window frame I i.

The means It are features of they invention.

ing of the cooler on the sill [l2 by the engagement of the flange 35 with the sill is such that there is a tendency for the cooler to swing downwardly and inwardly toward the external surface of the wall II). It is to be observed that the principal elements of the apparatus are spaced some distance outwardly from the wall It and the center of gravity of the cooler is quite remote from the mounting flange 35. Accordingly, there is a distinct tendency for the cooler to swing inwardly toward a non-horizontal position. The means It serve to support the casing I4 against this tendency.

There is one or more adjustable hearing or supporting means l8 engaged between the wall l and the cooler structure. In the preferred construction illustrated there is a means l8 associated with each rigid unit of the frame l5. Each means 18 includes a screw 44 passed through a horizontal opening in the lower portion of a frame member 23 and extending through a registering opening in the wall 2| of the casing l4. The screws 44 are of substantial length to project beyond the wall 2| and to project into the casing l4. A pad or foot 45 is secured on the outer end of each screw 44. The feet 45 are adapted to flatly bear against the wall ill. for the transmission of the load or forces to the wall. The feet 45 may have openings 46 for passing screws or other attaching elements so that they may be secured to the wall It. Two adjusting nuts are provided on each screw 44. One nut 41 engages against the frame member 23, while the other nut 41 is cooperable with the outer face of the casing wall 2|. It will be seen that by threading the nuts 41 along the screw 44 that the screw may be adjusted with respect to the casing l4. The screws 44 with their pads 45 may be individually adjusted so that they may both bear on the wall In to sustain or support the cooler in the position where the casing i4 is upright with its bottom horizontal. The individual adjustment of the screws 44 adapts the cooler for installation in practically any situation and provides for the uniform dependable mounting of the cooler where the wall I0 is of different thicknesses or is irregular. The pads or feet 45 of the screws 44 may be secured to the wall ID to prevent movement and vibration-of the cooler. It is to be observed that the feet 45 are positioned adjacent the lower portion of the cooler to bear on the wall ill at points a substantial distance from the axis about which the cooler tends to pivot to be particularly effective in sustaining the cooler. The screws 44 are directly secured to the rigid triangular frame units of the frame II to directly transmit the forces or loads from the frame tothe wall l0 thus relieving the casing l4 of all loads and strains which might tend to distort it.

its flange engages against theiinner edge or sill'.l2. The outer sealingsections 40 are then adjusted outwardly to engage with the sides of the, window frame H. The window 13 may then be lowered to the position where its lower edge engages the adaptor 34 and engages'the sealing sections 81 and ,40. The screwsv 44 are adjusted so that their ID to sustain or support the cooler in the correct upright position for operation. The nuts 41 may be employed to adjust the screws 44 and when the cooler has been adjusted to'the correct position the nuts are employed to set or look the screws in the adjusted ositions. The feet 45 may be secured to the wall In by screws or the like passed through the openings 46.. It

will be seen that the cooler may be very easily and quickly mounted in its correct operative position at window openings of various sizes and on wall structures of different kinds.
